PROTECTING DEVICE FOR GAS-STOVES.

Patented Nov. 22, 1910.

Application filed June 23, 1910. Serial No. 568,494.

ing stove for the purpose of protecting theeontrollingvalves of the stove so that they cannot be opened accidentally or inadvertently by small children.

My invention consists in certain details, in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a front elevation of a part of a gas stove with my protecting device applied thereto and in open position. Fig. 2 shows a similar View showing the protecting device in closed position, and Fig. 3 shows a transverse, sectional view with the protecting device in closed position, and its open position indicated by dotted lines.

Referring to the accompanying drawings, I have used the reference numeral 10 to 111-. dicate the part of a vapor or gas burning stove. 11 indicates a part of the main supply pipe for gas, and 12 indicates the supply pipes for the independent burners of the gas stove, each of which isprovided with an ordinary valve 13 for controlling it. All of these parts are of the ordinary construction now in general use.

in order to provide means whereby the valves may be iuclosed or protected in such a manner that they cannot become accidentally opened nor can they be inadvertently opened by children or unauthorized persons, I have provided on the supply pipe 11 two pivoted collars 14 and attached to said collars is a curved metal protecting device 15 designed in .one position to rest against a part of the stove front and also capable of swinging with the collars 14 to open position where the valves 13 will all be uncovered.

As an additional means for preventing accidental manipulation of the valves, I

have provided a lock 16 of ordinary construction on the hinged protecting device. This lock is designed to coact with a stationary lug 17 fixed to the supply pipe 11. Be neath the valves-13, I provide a stationary protecting plate 18 fixed to a part of the stove and extended to position adjacent-t0 the supply pipe so that the valves cannot be reached by a hand inserted upwardly be tween the burner supply pipes 12.

In practical operation and assuming that the protecting device is in its open position, as shown in Fig. 1, and by dotted lines in Fig. 3, then obviously the operator may manipulate the valves that control the burners in the ordinary manner. If it is desired to protect these valves against manipulation the operator may simply swing theprotecting strip to its closed position, as shown in Fig. 2, and by solid lines in Fig. 3, and insert a key in the'lock and turn the lock so that its slide bolt will engage with the lug 17 whereupon said protecting device will be held in its closed position and the valves will all be protected against being turned because of the protecting plate 18 below them and theprotecting device 15 above them which substantially inclosessaid valves on all sides to such an extent as to prevent a person from inserting his fingers betweenthe protecting device as required to turn the valves.

One of the principal advantages of my invention is that the valves'on an ordinary gas stove are arranged at such height that. small children can easily reach them and in many instances the valves are inadvertently opened by children. WVith my improved appliance, when in closed position, this is positively prevented even though the protecting device is not locked; hence the use of a positive lock and key is not essential but in certain instances is a desirable attachment.

I claim as my invention:

1. The combination of a stove, a supply pi po extended along the front of the stove, a

number of branch pipes projecting from the protect the valves when the shield is its closed position.

2; The combination of a stove, a supply pipe extended alon the front of the stove, a number of branc pipes projecting from and-towardthe stove and being designed to rest agains't'a portion of the stove front and also capable of"; swinging forwardly andthen downwardly, to 1 position below the v its.

valves and 7 below the stove top, a curved shield onls'aid arms designed to wholly cover and protect thevalves when the shield is in c osed p'ositionfa lock carried byv the shield, and a coactingstationary lug, wheresition.

3. The combination of a stove, a supply pipe extendedalon the front of the stove,

a number of, branc pipes projecting from by the shieldmay be'locked its closed po the supply pipe into the stove, a valve for each branch pipe, two arms havin their ends pivotally connected to the supp y pipe in front of the stove and curved u ward y and toward the stove and being esi ed to rest against a portion of the stove ront and also capable of swinging forwardly and then downwardly to position below the valves and below the stove top .a curved shield on said arms designed to wholl cover rotect the valves when the shie d is in and its c osed position, and a stationary plate secured to the 'stove front below the valves and extended to position adjacent to the supply pipe to prevent access being had to the valves from beneath,'. for the purposes stated. 1
